Is the "Scene Fragments" feature teased during GDC 2018 still in development?

I've rewatched the Unity 2018 Roadmap talk and here they show a prototype feature called "Scene Fragments". It's described as a feature to split up a scene into multiple assets which are more version control friendly. I assume that GameObjects in one fragment can still have references to GameObjects in other scene fragments. If this would work it would revolutionize my team's workflow. We've been struggling with scenes and multi-scene workflows and this scene fragments idea sounds really great.

This feature sounds almost too perfect and would solve so many issues larger teams currently face when dealing with either trying to collaborate on big scenes or having to maintain cross-scene-references when using many smaller scenes.

Is Scene Fragments still in development? How does it look? And is this in any way related to potential folder/grouping objects in the hierarchy?

I think they're probably talking about subscenes? I'm not sure.

 

To me it looks like scene fragments was dropped due to DOTS, but I don’t think that entities and co solve what scene fragments teasered. In the video they were speaking about splitting scenes with regular Gameobjects into multiple assets to make version control easier. This would kind of change the entire multi-scene workflow that existed in previous Unity versions because it sounded like cross-scene-fragment references would be possible in this setup. That would have been really great, but since we haven’t heard anything new, Unity is probably focusing on improving the DOTS scenes workflow.
